At present the only ref to "BA Connect" should, and as been on the flights I have flown on, during the welcome aboard PA. After that the service should be refered to as British Airways. After the 26th March all references should be "BA Connect". The exception to the rule is the LCY flights, which will still be "British Airways flight operated by BA connect" as they will continue to be full service two class flights.
So if it is said correctly there is NO deception there.
